1. A method for motion sensing carried out by a sensing responder including a transmitting antenna, a receiving antenna, and at least one processor configured to execute instructions, the method comprising:
receiving, by the at least one processor from a sensing initiator, a sensing configuration comprising a time 0 reference point and a maximum time delay;
obtaining time domain channel representation information;
selecting, according to the time 0 reference point and the maximum time delay, one or more time domain pulses of the time domain channel representation information as selected time domain pulses;
generating a bitmap according to the selected time domain pulses; and
generating a sensing measurement report including at least the bitmap and the selected time domain pulses.
